SK Hynix Wobbles as Solidigm IPO Talk Collides With a Market-Wide Pullback

SK Hynix considers a US listing of NAND unit Solidigm by 2027, even as foreign selling and dilution worries pull its Seoul shares lower.

Two forces are pulling SK Hynix in opposite directions right now, and neither one has much to do with the memory chips the company actually sells. On one side sits an ambitious plan to float its NAND subsidiary Solidigm on a US exchange by 2027 — a deal that could raise roughly USD 10 billion against a valuation of up to USD 100 billion. On the other sits a broad retreat by overseas investors that knocked 2.8 percent off the Seoul-listed stock in a single session, leaving it at KRW 1,723,000.

The contrast is hard to miss. SK Hynix picked up the NAND flash business from Intel for USD 8.85 billion, so the numbers being floated for a Solidigm listing imply a spectacular paper gain. Bloomberg reports that Goldman Sachs and Morgan Stanley have been tapped to lead the offering, with JPMorgan Chase, Citigroup and UBS expected to round out the syndicate.

Shareholder Dilution Fears Take Center Stage

Investors are not celebrating. In Seoul, warnings are growing that a standalone listing could hollow out the parent company. Lawmaker Ahn publicly pressed SK Group chairman Chey to clarify the plans, flagging the risk of dilution for existing shareholders. The conglomerate discount is a genuine concern: when a high-margin subsidiary lists separately, the parent's own valuation often suffers.

Management has moved to contain the fallout, stressing that no decision has been finalized and that protections for current shareholders are under review. That message was repeated about a week ago, when the company made clear it was still weighing financing options and their consequences for existing investors.

The timing could hardly be more awkward. SK Hynix is nearing the end of a KRW 40 trillion buyback program, with the repurchased shares slated for full cancellation. Fund managers at Franklin Templeton recently rated the company ahead of its peers on shareholder returns. Launching a spin-off while that program is still running looks like a strategic about-face.

A Correction, Not a Collapse

The recent share price weakness has little to do with Solidigm, though. Foreign investors sold broadly across the Korean market, dragging the stock to its KRW 1,723,000 close. A cluster of pressures explains the caution: the approaching expiry of a lockup period, thinner liquidity at home, and worries that a stronger won will eat into export margins. Provisions for employee bonuses added to the hesitancy ahead of third-quarter results.

Sector sentiment did not help. Concerns surrounding Toshiba weighed on memory names, and many traders chose to sit on their hands before Samsung Electronics published preliminary quarterly figures. When two heavyweights of a key industry are about to report, international accounts typically trim exposure first.

None of this points to a company-specific problem. The stock is still up 165 percent year to date, and pullbacks after that kind of run are a normal part of market mechanics — they let some air out of overheated expectations before the next set of hard numbers arrives.

Fundamentals Remain Intact

The demand picture for high-performance memory has not dimmed. SK Hynix chief Kwak Noh-jung predicted over the summer that demand would outstrip the company's production capacity beyond 2030. IBK Investment & Securities reiterated its buy rating with a KRW 4 million price target, noting that SK Hynix intends to return at least half of its free cash flow after capital expenditure to shareholders.

Meanwhile, the NAND unit is expanding its manufacturing base in Taiwan for data-center SSDs, a move aimed at serving the supply chain for AI servers. The gap between the stock's summer peak of KRW 2,987,000 and today's level — a decline of 42 percent — reflects how much optimism has already been unwound, even as the operational story holds steady.

What SK Hynix's leadership must now demonstrate is that financing the US expansion will not come at the expense of the shareholders who carried the company through the cycle. A listing that breeds distrust would ultimately defeat its own purpose.
